In Washington, President Barack Obama and Congress are engaged in high-drama brinksmanship, like members of an ordnance-disposal unit arguing about how to defuse a huge ticking bomb. Obama, securely in character, called on all sides to rise above petty politics, acknowledged the practical realities of divided government, and proposed a grand compromise that would lower the deficit by four trillion dollars. According to the Times’ Nate Silver, Obama’s offer, in its roughly four-to-one balance between spending cuts and revenue increases, falls to the right of the average American voter’s preference; in fact, it may outflank the views of the average Republican. Among other drastic cuts to domestic spending, the President proposes a ten-year, hundred-billion-dollar reduction in federal contributions to Medicaid. …

The Republicans are also securely in character. They’ve rejected everything that the President has proposed, because Obama’s deal includes tax increases and the closing of loopholes for hedge-fund managers and corporate jets and companies that move offshore. Ninety-seven per cent of House Republicans have taken something called the “No Tax Pledge. …”

The sociologist Max Weber, in his 1919 essay “Politics as a Vocation,” drew a distinction between “the ethic of responsibility” and “the ethic of ultimate ends”—between those who act from a sense of practical consequence and those who act from higher conviction, regardless of consequences. These ethics are tragically opposed, but the true calling of politics requires a union of the two. On its own, the ethic of responsibility can become a devotion to technically correct procedure, while the ethic of ultimate ends can become fanaticism. Weber’s terms perfectly capture the toxic dynamic between the President, who takes responsibility as an end in itself, and the Republicans in Congress, who are destructively consumed with their own dogma. Neither side can be said to possess what Weber calls a “leader’s personality.” Responsibility without conviction is weak, but it is sane. Conviction without responsibility, in the current incarnation of the Republican Party, is raving mad.
